First, my compliments to the makers of the Evolve Theme. It reflects weeks of quality work and is very generously given free.
There is a bug in the Evolve Theme in that the Title of the Blog Appears twice in the RSS feed.
The Title to the RSS feed reads as follows:
Blog TitleBlog Title
To solve the problem, open the basic.functions.php file in the wp-content/themes/evolve/library/functions folder, go to line 339 (or thereabouts) and find the line:
$filtered_title = $site_name . $title;
and comment it out by placing "//" at the beginning of the line.
This solves the problem. I don't think it breaks anything.
Interestingly, the same line, with the same problem appears also in the "Pure Line" theme. These lines are not there in the "Precisio" theme.
